Magic-angle sample spinning (MAS) has had a major impact on several aspects of the development of NMR and its application to solid state physics and chemistry. MAS was first used to average out dipolar broadening in 23Na NMR of monocrystalline sodium chloride, as published in 1958 by Andrew, Bradbury and Eades [1]. After that many more examples were published in the early days including applications to other nuclei such as 1H [2] and 31P [3]. However, successful applications of MAS required either a substantial motional narrowing in the case of strong homonuclear dipole broadening, or a dominant inhomogeneous line broadening interaction such as the chemical shift anisotropy.
